How Can an Accelerated Movement Be Generated

Abstract

From that which was explained above, it appears that an accelerated movement is generated by a gradually increasing impetus. The flow of this increasing impetus makes the surface of the impetus triangular. Therefore, the distances travelled in unequal times are proportional to the surfaces themselves of the velocities and, consequently, the ratio of the travelled distances is greater than that of the times of the travels, i.e. this ratio is the product of the ratio of the times and the ratio of the arithmetic average velocities of the unequal impulses. It thus must be sought for why and how an impetus can always grow and increase. An impetus of course is generated by the impulse of a body provided with a motive force.
